Question

Why is it wrong to say " a child of six years old" and is possible to say "a six-year-old child"?

Example: My family consists of /is made up of/ is composed of two adults and two children, six years old and ten years old.
But: .... of a six-year-old child and a ten-year-old child?


Can you please recommend me a nice and convenient four-star accommodation in West Yellowstone which lies not too far from the park? Thank you for your help!!

Answer 1

There are several ways to say that, but "of" is used the least. It's not actually incorrect; it's simply awkward (has that extra, unneeded word).

... a child of six.

... a child who is six years old.

... a six-year-old child.

Or try this ...
My family is made up of two adults and two children, ages six and ten.

Hotels marked with C, G, and D seem to be the closest ones to the park's west entrance. All would be interesting to investigate, but I'd focus on those three.
